What Researchers Did
Researchers investigated the mobilization of stem/progenitor cells and effects on platelet activation in ten head and neck irradiated patients undergoing hyperbaric oxygen treatment for radiation tissue injury.
What They Found
They found a weak and insignificant tendency for CD34+CD45dim cell mobilization after a single hyperbaric oxygen exposure. An additive effect was observed after 15 exposures, increasing CD34+CD45dim cells by less than a doubling, but no significant effect was seen on Aldefluor® positive stem cells or overall platelet activation.
What This Means for Canadian Patients
For Canadian patients receiving hyperbaric oxygen for radiation injury, this study suggests that significant stem cell mobilization is unlikely to be a primary therapeutic mechanism. Patients should not expect substantial stem cell benefits from this treatment based on these findings.
Canadian Relevance
This study has no direct Canadian connection as indicated by the metadata.
Study Limitations
The study's primary limitation is its very small sample size of ten patients, which limits the generalizability and statistical power of the findings.
